The book presents a unified and well-developed approach to the dynamics
of angular motions of rigid bodies subjected to perturbation torques of
different physical nature. It contains both the basic foundations of the
rigid body dynamics and of the asymptotic method of averaging. The
rigorous approach based on the averaging procedure is applicable to
bodies with arbitrary ellipsoids of inertia. Action of various
perturbation torques, both external (gravitational, aerodynamical, solar
pressure) and internal (due to viscous fluid in tanks, elastic and
visco-elastic properties of a body) is considered in detail. The book
can be used by researchers, engineers and students working in attitude
dynamics of spacecraft.
